EC Number	Natural Substrates	Commentary (Nat. Sub.)
3.2.1.157	iota-carrageenan + H2O	-
3.2.1.157	iota-carrageenan + H2O	yielding neo-iota-carratetraose as the main product in the absence of NaCl
3.2.1.157	more	kappa-, iota- and lambda-carrageenase display strict specificity for their substrates, namely kappa-, iota- and lambda-carrageenans, respectively. The enzymes discriminate the substrate probably by recognizing the sulfation pattern of the digalactose reapeting unit of the polysaccharide. iota-Carrageenas present conserved arginine residues in the catalytic site which are believed to interact with carrageenans in which both sugar residues in the disaccharide units are negatively charged
3.2.1.157	more	the supernatant of marine bacterium Pseudoalteromonas carrageenovora ASY5 can degrade iota-carrageenans and kappa-carrageenans (EC 3.2.1.83)
